The pancreatic endocrine cells, glucagon and somatostation, of the Korean tree squirrel. Sciurus vulgais corea, were investigation by means of light and electron microscopic immunohistochemistry using the PAP and protein A-gold techniques. Glucagon-immunoreactive cells were distributed the periphery and occasinonaly central region of the pancreatic islets. Also, isolated cell was found between the pancreatic ancinar cells. The glucagon cells contraine granules with a diameter of 240~320nm and the electron dense core usually surrounded by a halo of less dense granular material. The core of granule was labelled strongly with gold particles. Somatostatin-immunoreactive cells were weakly stained in scattered along the peripheral pancreatic islets and were distributed as singly or small groups with in the pancreatic acinar cells. The somatostatin cells were spherical with a diameter of 250~275nm, moderately electron opaque (Gold particles were mostly demonstrated on the entire granule.
Key Words: Korean tree squirrel, glucagon, somatostatin, pancreas, protein A-gold technique
